Abstract. Ceramic membrane filter consisting of the filtration layer obtained from natural diatomite particles (finer than 50 μm) by coating onto a large porosity support made of quartzbased materials was fabricated. The coating was achieved by pressure filtration at 5 bar and later sintering applied at 600 °C.
